Title: Absorbent article with a flap and spacer
Inventor: TURNER LAURA JEAN
IPC: A61F13/15
Filed: 2000-02-04
Abstract: An absorbent article having a flap and a spacer wherein the flap is positioned in the rear waist portion of the article and forms a pocket. The spacer is positioned proximate the pocket opening and biases the pocket into an open position. The flap may be a laterally extending liquid impermeable flap which is fixedly secured to the article along a seam. The seam, which may be substantially U-shaped, extends between first and second terminal ends. The flap has a free edge which extends between the first and second terminal ends of the seam. The seam and free edge of the flap define the boundaries of a pocket which is formed between the flap and a topsheet of the absorbent article. The pocket has an opening extending between the first and second terminal ends of the seam. The spacer affixed to the article whereby it is disposed between the flap and the topsheet proximate, and optionally extending through, the pocket opening to bias the free edge of the flap away from the topsheet. Alternative spacer embodiments may be employed. A single spacer or two spacers positioned on opposite sides of the longitudinal axis of the article may be used to bias the pocket open. The spacers may extend across a substantial lateral length of the opening and have a plurality of topsheet and flap engagement surfaces as exemplified by helical and folded planar spacers. The spacer assembly may also include two arms which I gave a laterally inward facing surface which, over a substantial length of the inward facing surface, extends laterally inward as the inward facing surface extends longitudinally forward to facilitate the retention of fecal materials within the pocket. The spacer may also dynamically bias the flap away from the topsheet whereby the size of the pocket opening is automatically adjusted in response to relative movement between the wearer and the absorbent article. One or more hinged spacers may be employed to provide such a dynamic spacer.

Inventor: BOROWSKI JOE P
IPC: B65G33/32
Filed: 2000-06-20
Abstract: An attachment is used on a bin sweep of a type having inner and outer sections of auger flighting and a backboard along the outer section of flighting. The attachment includes a shield that extends along the back of the inner section of flighting to control the accumulation of material around the inlet to a loading auger with which the bin sweep is used. The shield is attached to the pivot mount for the bin sweep with a coupling allowing the movement of the shield with respect to the inner flighting section. It is connected to the backboard of the outer flighting section using a flexible joint that allows substantially universal movement of the shield on the backboard. This allows the flexing of the bin sweep as necessary at the universal joint between the inner and outer flighting sections and substantially reduces the accumulation of material in a pile between the inner end of the backboard and the loading auger.

Abstract: Monoclonal antibodies (in particular, P2L-1Ca) against 19P2 ligand having an extremely high avidity and being capable of neutralizing the arachidonic acid metabolite-releasing activity of the 19P2 ligand. Thus, these antibodies are usable in diagnostics, preventives, remedies, etc. for various diseases in association with abnormalities in the pituitary function regulatory mechanism (for example, promotion of the prolactin secretion), the central nerve regulatory mechanism, the pancreatic function regulatory mechanism, etc. The 19P2 ligand or its derivatives can be specifically quantitated at a high sensitivity by an immunoassay method based on the sandwich method with the use of the above-mentioned monoclonal antibodies (in particular, the sandwich method with the use of the monoclonal antibody together with an antibody recognizing the intermediate part of the 19P2 ligand). This quantitating method is usable in clarifying the physiological functions of the 19P2 ligand or its derivative.

Title: Direct customer control of a network router
Inventor: MATHEWS EUGENE P
IPC: H04L12/56
Filed: 2000-12-19
Abstract: An entity of a private communications network, such as a controller of an ACD system, controls the operation of a network router of a public communications network, thereby eliminating the need in a network-routing system to send sensitive event or status information of the private network to the network router. The entity collects and processes locally the status information about the private network, and whenever it detects that the workload balance in the private network needs readjusting, it sends a new routing sequence message to the network router. These messages specify the routing scheme to the network router. A routing sequence message contains a pair of routing sequences. Each is an ordered sequence of destination route points. The first establishes a load balance and the second maintains the load balance. The first is executed by the network router once upon receipt, and the second is executed repeatedly in a cycle until a new routing sequence message is received.

The screw (27) has three zones (29, 31, 33), a feeding zone (29), a compression zone (31) and a metering zone (33), and the depth and pitch of the flights (43, 45, 47) of the screw (27) are designed based upon the material to be used in the screw (27) so that the difference in the ratio of the actual flow to the theoretical drag flow of material in the feeding zone (29) and the ratio of the actual flow to the theoretical drag flow of material in the metering zone (33) is less than 0.2, preferably less than 0.1, and more preferably less than 0.05. This design results in a screw (27) which has a balanced mass flow, and thus a constant pressure gain along the screw without pressure peaks.
